Examples of UE devices include mobile phones or smartphones (e.g., iPhone, Android-based phones), portable gaming devices (e.g., Nintendo DS, PlayStation Portable, Gameboy Advance, iPhone), laptops, PDAs, portable Internet devices, music Players, data storage devices, or other handheld devices, etc. In general, "UE" may be broadly defined to encompass any electronic, computing, and/or telecommunications device (or combination of devices) that is conveniently transported by a user and capable of wireless communication.

Base station, has the full scope of its ordinary meaning, and includes at least a wireless communication station installed at a fixed location and used to communicate as part of a wireless telephone system or radio system.

Mobile phone card, including but not limited to SIM (Subscriber Identity Module, user identification card), USIM (Universal Subscriber Identity Module, global subscriber identification card), RUIM (Removable User Identity Module, removable user identification card), UIM (User Identity Module, user identification card), etc.

Fig. 1 shows a wireless communication system, and the system shown in Fig. 1 is only an illustrative example. The wireless communication system includes a user equipment 11 , a server 10 and a base station 13 .

User equipment 11 may communicate using one or more RATs. For example, LTE, WCDMA, CDMA2000, TD-SCDMA, GSM, CDMA, etc.

The server 10 is used to provide data statistics and analysis services for the UE. The server 10 may be provided by a manufacturer or seller of the UE, or by a developer of an operating system or an application program installed on the UE.

The user equipment 11 may be connected to the Internet (Internet) through WIFI (WIreless-Fidelity) or a data network, so as to establish a communication connection with the server 10 for data interaction. The user equipment 11 can access the mobile communication network through the base station 13 .

In the embodiment of the present invention, the user equipment 11 records the frequency points when the machine successfully accesses the RAT under each PLMN, and counts the successful access probability of each frequency point, generates the first frequency point preference list and uploads it to the server 10, and the service The terminal 10 collects the first frequency point preference table uploaded by each user equipment 11, calculates the successful access probability of each frequency point through statistical analysis and generates a second frequency point preference table, and the user equipment 11 obtains the frequency point preference table from the server according to the location information of the device. 10. Obtain the second preferred frequency table of the PLMN corresponding to the location information. When the user equipment 11 enters the roaming state at the corresponding location, after determining the selected PLMN and the registered RAT and failing to scan according to the latest registered frequency list, By querying the second frequency point preference table to select a frequency point with a higher access probability to try to access, it avoids the process of scanning the entire frequency band of the RAT after failing to scan according to the latest registered frequency point list, thereby shortening the frequency point scan time-consuming.

For the user equipment 11, an embodiment of the present invention provides a communication network access method, as shown in FIG. 2 , the method includes the following steps.

S20, make statistics on the frequency points when the machine successfully accesses the RAT under each PLMN, generate a first frequency point preference table, and record in the first frequency point preference table that the access probability under the corresponding RAT is greater than or equal to the preset threshold Frequency.

The UE can count the local network access data through the baseband processor. In the embodiment of the present invention, the frequency points when the UE successfully registers the RAT under each PLMN are recorded, and the successful access probability of each frequency point is counted. For example, when the UE accesses LTE under PLMN45403, the frequency points include 1750, 1825, 100, etc., then, the UE further calculates the successful access probability of each frequency point according to the number of access times of each frequency point.

S21. Upload the current location information of the device and the first frequency preference table to the server, so that the server can perform statistical analysis on the first frequency preference tables uploaded by each terminal, and generate a second frequency preference table.

The UE can upload its current location information and the first frequency point preference list to the server periodically or automatically or triggered by the user, and the server will store the current location information of the machine and the first frequency point preference list correspondingly. After the server collects the first frequency point preference list uploaded by each UE, it will perform further statistical analysis, and readjust the successful access probability of each frequency point according to the statistical results of each first frequency point preference table, so as to pass The data uploaded by more UEs will get more accurate statistical results. A second frequency point preference table corresponding to each location information is generated according to the adjusted statistical results.

S22. Obtain a corresponding second frequency point preference list from the server according to the location information.

The location information may be country, city, station, airport and other information. The location information may be the current location of the user equipment, or may be the location that the user equipment will arrive in a certain period of time in the future. That is to say, after the user equipment arrives at the roaming location, it can request the server to obtain the second frequency point preference list corresponding to the various RATs under the PLMN corresponding to the location information through the location information of the user equipment. Before, request the server to obtain the second frequency point preference list corresponding to the location information through the location information that the machine will arrive.

There may be one or more operators in one location, so the second RAT preference table corresponding to each location information will include one or more PLMNs. .

S23. When entering the coverage area of the communication network corresponding to the location information and failing to scan the accessible frequency points according to the recently registered frequency point list, scan the frequencies under the registered RAT according to the second frequency point preference table and complete network access.

After the UE arrives at the corresponding location, it will access the local communication network, and there are usually multiple operators in the local area, that is, corresponding to multiple PLMNs. In the process of accessing the local communication network, the selection of the PLMN and the registration of the RAT can be completed according to the process described in the existing standard protocol.

After determining the PLMN used and the registered RAT, scan the accessible frequency point through the recently registered frequency point list saved in the nonvolatile item (nonvolatileitem, nv item), if no accessible frequency point is scanned, then According to the used PLMN and the registered RAT, query the corresponding frequency point in the second frequency point preference table and try to access it. Since the second frequency point preference table records the frequency points whose access probability is greater than or equal to the preset threshold, the possibility of accessing the network through these frequency points is very high, avoiding the need to scan for accessible frequency points in the recently registered frequency point list After the failure, the full-band scanning process is performed on the registered RAT, thereby shortening the time of frequency point scanning, so that after the UE determines the PLMN to be used and the registered RAT in the roaming state, it can quickly pass through the second frequency point preference table from the server. Scanning the access frequency point also shortens the time-consuming for the UE to access the local communication network.

Preferably, in the second frequency point preference table in the embodiment of the present invention, the frequency points under each RAT are arranged in descending order according to the probability of successful access, and when the UE queries the second frequency point preference table, it will also Try scanning in that order.

In addition, during the running process of the UE, the first frequency preference table recorded by the UE can also be used.

When the UE enters the international roaming state in the power-on state, the UE reselects the available PLMN and the registered RAT according to the standard protocol, and then scans the accessible frequency point according to the recently registered frequency point list and fails, it will be in the first frequency point preference table Query the frequency points under the PLMN selected for use and the registered RAT, and scan in order of access probability from large to small to complete network access.

In this way, when entering the international roaming state in the power-on state, it is also possible to access the local communication network faster through the first frequency point preference table after determining the selected PLMN and the registered RAT.

In the above-mentioned embodiments, the selection of the PLMN and the registration of the RAT by the UE are completed according to the standard protocol, that is, first try RPLMN, then try EPLMN or EHPLMN, and then try UPLMN, OPLMN, PPLMN, etc. to determine the PLMN to use Finally, try to register various RATs under the PLMN in order of priority from high to low. In order to shorten the time consumption of PLMN selection and RAT registration, when requesting the server for the second frequency point preference list according to the location information of the local device, the shared PLMN list can be requested at the same time.

The shared PLMN list is obtained by the server after statistical analysis of network access data uploaded by multiple UEs.

The server collects network access data uploaded by multiple UEs, performs statistical analysis on communication network access information at different locations, and obtains information such as PLMN, RAT, frequency point, and cell of the communication network that can be accessed at each location. A shared PLMN list is generated for different locations. For a location, the more network access data collected by the server, the higher the accuracy of the shared PLMN list.

The shared PLMN list includes any one of the OPLMN list, UPLMN list, PPLMN list, EPLMN list and EHPLMN list.

After the UE obtains the shared PLMN list, it judges whether the PLMN identifier in the shared PLMN list exists in the PLMN list corresponding to this machine, and adds the PLMN identifier that does not exist in the PLMN list corresponding to this machine to the PLMN list corresponding to this machine, And complete the updating of the PLMN list corresponding to this machine.

The PLMN list updated by the user equipment corresponds to the shared PLMN list obtained from the server, and may be any one of the OPLMN list, UPLMN list, PPLMN list, EPLMN list and EHPLMN list.

The UE can identify whether it is roaming internationally according to whether the MCC of the local communication network changes, or identify whether it is roaming domestically according to the location code.

For example, the non-access stratum (Non Access Stratum, NAS) issues RPLMN high-priority RAT registration; layer 1 (Layer 1, L1), that is, the physical layer, searches the RPLMN network according to the fast search frequency point table, and generates a list of available networks, If the MCC in the available network list is different from the MCC in the RPLMN, it indicates the roaming destination; notify the NAS, and the NAS registers with the PLMN corresponding to the new MCC in the updated PLMN list in the mobile phone card.

After it is identified that it is in a roaming state, it does not search the network through the RPLMN in the memory, but performs a network search and completes the access according to the updated PLMN list. In this way, the process of scanning the entire frequency band for various RATs in the saved RPLMN is skipped, unnecessary PLMN registration attempt time is avoided, the speed of starting up and searching for the registered network in the roaming state is accelerated, and the multi-mode terminal user experience is improved.

The shared PLMN list may include PLMN identities of one or more countries, for example as shown in the following table:

Different PLMN identifiers come from different local operators, so in order to further improve the hit rate of the PLMN identifier, in another embodiment, the shared PLMN list includes the operator of the visited location that has signed a roaming agreement with the operator of the mobile phone card of the user equipment. The PLMN logo of the provider. This shared PLMN list is obtained by the server after performing statistical analysis on network access data uploaded by multiple UEs.

In the state of international roaming, the user equipment can directly query the PLMN identifier of the visited operator that has signed a roaming agreement with the operator of the local mobile phone card from the shared PLMN list through the MCC in the available network list and complete the network access, thereby saving The process of trying the PLMN identities of different operators under the same MCC is eliminated, and the speed of starting up and searching for the registered network in the roaming state is further improved.

After determining the PLMN to be accessed, the UE continues to try to register according to the RAT priority, and will try a lower priority RAT after rejecting a certain number of times. In order to further improve the communication network access efficiency, in another embodiment, the shared PLMN list It also includes one or more RATs corresponding to each PLMN identifier. The one or more RATs are obtained by the server through statistical processing of network access data uploaded by multiple terminals, and are the corresponding PLMN RAT that has activated roaming service under the identifier.

Sometimes, some operators do not subscribe to the roaming service of the high-priority RAT, for example, LTE and WCDMA do not subscribe to the roaming service, and GSM subscribes to the roaming service. Then, high-priority LTE and WCDMA are not recorded under the PLMN identifier, and only GSM with roaming service enabled is recorded. When the UE tries to access the RAT, it directly tries GSM, and no longer tries to register LTE and WCDMA without roaming services, thereby reducing unnecessary searching and registration attempt time. If the subsequent operator increases the RAT priority of the subscribed roaming service, the server can update the shared PLMN list by collecting the network access data of each UE, and add the newly signed RAT with higher priority. The shared PLMN list in this embodiment is shown in the following table, for example:

PLMN RAT 45403 LTE WCDMA 45404 GSM ... ... 46000 TD-SCDMA GSM 46001 GSM

When entering the communication network coverage area corresponding to the location information, quickly determine the selected PLMN and registered RAT according to the updated PLMN list;

When scanning the accessible frequency points according to the recently registered frequency point list stored in the non-volatile item fails, scan the frequency points under the registered RAT according to the second frequency point preference table and complete the network access.

While realizing the fast selection of PLMN and the fast registration of RAT by sharing the PLMN list, when scanning the accessible frequency points in the latest registered frequency point list fails, use the second frequency point preference list obtained from the server to scan the registered RAT frequency points and complete network access, which can further reduce the time-consuming communication network access process in the roaming state.

As shown in Figure 3, an embodiment of the present invention provides a communication network access device, including:

The statistical module 111 is used to make statistics on the frequency points when the machine successfully accesses the RAT under each PLMN, generates a first frequency point preference table, and records in the first frequency point preference table that the access probability under the corresponding RAT is greater than or equal to The frequency point of the preset threshold;
